Description

Technical Field

[0001] This invention relates to the field of model aircraft deceleration parachute design, and more particularly to a model aircraft deceleration parachute system and its usage method. Background Technology

[0002] Model airplanes generally refer to models that can fly in the air. They typically require a runway distance to come to a stop after landing, especially jet-powered model airplanes, which tend to land at high speeds, resulting in a long runway distance and potentially causing them to overshoot the runway and be damaged. Therefore, the applicant has added a drag chute device to the model airplane to slow it down after landing, shorten the runway distance, and allow it to stop quickly, thus increasing its playability.

[0003] Since the deceleration parachute device is controlled by a servo motor, the servo motor needs to be reset before the deceleration parachute can be recovered. Based on this, the applicant has achieved the ability to recover the parachute before the servo motor needs to be reset through a clever mechanical structure. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a model aircraft drag chute system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention relates to a model aircraft deceleration parachute system, including a parachute cover, an unlocking component, and a servo motor. The servo motor can control a rocker arm to push the unlocking component away from the parachute cover. The unlocking component includes a switch push block, a rotating shaft, a rotating component, and a torsion spring. The switch push block is provided with a switch mounting slot. The rotating component, in conjunction with the rotating shaft, is oscillatingly mounted in the switch mounting slot. The top of the rotating component is provided with a torsion spring mounting slot. The rotating shaft passes through the torsion spring mounting slot. The torsion spring, in conjunction with the rotating shaft, is set in the torsion spring mounting slot. The torsion arm of the torsion spring abuts against the bottom of the torsion spring mounting slot, and the torsion arm pushes the rotating component against one side of the switch mounting slot.

[0006] Preferably, the unlocking component further includes a reset spring, one end of the switch push block is provided with a hook for connecting and cooperating with the umbrella cover plate, and the other end of the switch push block is provided with a spring mounting post, and the reset spring is sleeved on the spring mounting post.

[0007] Preferably, the bottom of the rotating component is provided with a first pushing surface and a second pushing surface for the rocker arm to push, the first pushing surface facing the hook head and the second pushing surface facing the spring mounting post.

[0008] Preferably, the umbrella cover is provided with a buckle, the buckle is provided with a first inclined surface, and the hook head is provided with a second inclined surface that matches the first inclined surface.

[0009] Preferably, it also includes a deceleration parachute cabin, a deceleration parachute pack, and a parachute ejection device. The deceleration parachute cabin is provided with a parachute pack slot, and the bottom of the parachute pack slot is provided with a parachute ejection device. The deceleration parachute pack is placed on the parachute ejection device. The opening of the parachute pack slot is provided with a parachute pack cover plate that can be opened or closed. The parachute ejection device provides thrust to push the deceleration parachute pack against the parachute pack cover plate.

[0010] Preferably, the deceleration parachute housing is provided with a first groove and a second groove, the first groove and the second groove are respectively provided on both sides of the parachute pack slot, a tension spring is provided in the first groove, the tension spring is connected to the parachute pack cover plate, and the unlocking component and the servo motor are fixedly provided in the second groove.

[0011] Preferably, the umbrella cover includes a fixed end and a free end. The fixed end is flip-top disposed between the umbrella slot and the first groove. When the umbrella cover closes the umbrella slot, the free end enters the second groove. The free end is provided with a buckle, and the buckle has a buckle opening.

[0012] Preferably, the parachute ejection device includes a parachute push block, an ejection spring, a spring fixing block, and a spring fixing seat. The spring fixing seat is installed at the bottom of the parachute slot. One end of the ejection spring is fixed to the spring fixing seat, and the other end of the ejection spring is connected to the parachute push block in conjunction with the spring fixing block. The deceleration parachute is placed on the parachute push block, and the spring force provided by the ejection spring pushes the parachute push block, which then presses the deceleration parachute against the underside of the parachute cover.

[0013] Preferably, it also includes a hatch, which is hinged and mounted on the deceleration parachute hull.

[0014] Preferably, the hatch is made of a metallic magnetic material, and the deceleration parachute body is provided with a magnet mounting base, which is provided with a plurality of magnets for attracting the hatch.

[0015] The present invention also relates to a method for deploying and recovering a deceleration parachute, which includes the following steps:

[0016] S1. Deceleration Parachute Departure: The servo motor drives the rocker arm to rotate. As the rocker arm rotates, the rotating component pushes the switch push block backward, thereby disengaging the switch push block from the parachute cover. This releases the switch push block from the parachute cover, and the parachute ejection device ejects the deceleration parachute after it breaks through the parachute cover and the hatch. At the same time, the switch push block resets forward.

[0017] S2. Deceleration Parachute Pack Retrieval: Press the deceleration parachute pack into the pack slot. After the pack cover plate closes to the pack slot, the switch push block locks the pack cover plate. Start the servo motor to drive the rocker arm to rotate. The rotating part rotates under the push of the rocker arm. After the rocker arm resets, the rotating part automatically rotates back to its original position.

[0018] The present invention also relates to a model aircraft, wherein the model aircraft is provided with a deceleration parachute housing mounting slot, and the model aircraft deceleration parachute system is disposed on the model aircraft.

[0019] The beneficial effects of the present invention are as follows: The present invention relates to a model aircraft deceleration parachute system. In the present invention, the servo motor controls the rocker arm to push the unlocking component to disengage from the parachute cover plate, so that the parachute cover plate opens the parachute slot. The parachute ejection device provides thrust to push the deceleration parachute outward, so that the deceleration parachute pops out of the parachute slot. The deceleration parachute after popping out provides a deceleration effect to the model aircraft.

[0020] In this invention, the deceleration parachute pack can be directly installed into the pack slot before the rocker arm is returned to its original position via a servo motor. When the rocker arm returns to its original position, it pushes the second push surface of the rotating component, causing the rotating component to swing backward due to the thrust. Once fully returned to its original position, the rocker arm disengages from the rotating component, and under the torque of the torsion spring, it pushes the rotating component back to its original position, preparing for the next parachute deployment. This invention eliminates the need to first return the rocker arm to its original position before installing the deceleration parachute pack, effectively simplifying the operation and improving the user experience.

[0044] Please see Figure 1-16As shown, this invention relates to a model aircraft deceleration parachute system. The model aircraft deceleration parachute system 100 is mounted on a model aircraft 200 and includes a deceleration parachute housing 1, a deceleration parachute pack 2, a parachute ejection device 3, a parachute pack cover 4, an unlocking component 5, a rocker arm 6, and a servo motor 7. The deceleration parachute housing 1 has a parachute pack slot 11 for accommodating the deceleration parachute pack 2. The bottom of the parachute pack slot 11 is provided with the parachute pack ejection device 3. The deceleration parachute pack 2 is placed on the parachute pack ejection device 3, and the parachute pack ejection device 3 provides thrust to push the deceleration parachute pack 2 against the parachute pack cover 4. The opening of the parachute pack slot 11 is provided with a parachute pack cover 4 that can be opened or closed. The unlocking component 5 is mounted on the deceleration parachute housing 1 and is connected to the parachute pack cover 4. The servo motor 7 is mounted on the deceleration parachute housing 1 and controls the rocker arm 6 to push the unlocking component 5 away from the parachute pack cover 4, causing the parachute pack cover 4 to open the parachute pack slot 11.

[0045] When the servo motor 7 controls the rocker arm 6 to push the unlocking component 5 away from the parachute cover plate 4, the parachute cover plate 4 opens the parachute slot 11. Since the parachute ejection device 3 is not resisted by the parachute cover plate 4, the parachute ejection device 3 provides thrust to push the deceleration parachute 2 out of the parachute slot 11, so that the deceleration parachute 2 pops out of the parachute slot 11. After popping out, the deceleration parachute 2 provides a deceleration effect to the model aircraft 200.

[0046] In this embodiment, the deceleration parachute housing 1 is provided with a first groove 12 and a second groove 13, which are respectively located on both sides of the parachute pack slot 11. The parachute pack cover 4 includes a fixed end 41 and a free end 42. The fixed end 41 can be flipped up and positioned on the side of the parachute pack slot 11 near the first groove 12. When the parachute pack cover 4 closes the parachute pack slot 11, the free end 42 enters the second groove 13. The free end 42 is provided with a buckle 421, which has a buckle opening 422 that cooperates with the unlocking component 5.

[0047] Furthermore, a tension spring 121 is provided on the wall of the first groove 12. The tension spring 121 is connected to the umbrella cover plate 4. When the unlocking component 5 releases the umbrella cover plate 4, the elastic potential energy of the tension spring 121 pulls the umbrella cover plate 4, causing the umbrella cover plate 4 to open the umbrella groove 11.

[0048] Furthermore, the unlocking component 5 and the servo motor 7 are disposed within the second groove 13. The servo motor 7 is equipped with a rocker arm 6 for pushing the unlocking component 5 away from the latching opening 422. The unlocking component 5 is fixed within the second groove 13 by a switch bracket 56, and the second groove 13 is provided with a switch cover 131 to protect internal components. The unlocking component 5 includes a switch push block 51, a rotating shaft 52, a rotating component 53, a torsion spring 54, and a return spring 55. The switch push block 51 is provided with a hook head 511, a switch mounting groove 512, and a spring mounting post 513 sequentially from end to end. The hook head 511 is used to engage with the latching opening 422. The rotating component 53 and the torsion spring 54 are mounted within the switch mounting groove 512 in conjunction with the rotating shaft 52. One end of the return spring 55 is sleeved on the spring mounting post 513, and the other end of the return spring 55 abuts against the wall of the second groove 13.

[0049] The rotating component 53 has a torsion spring mounting groove 531 at its top for mounting the torsion spring 54. The rotating shaft 52 passes through the torsion spring mounting groove 531, and the torsion spring 54 is mounted in the torsion spring mounting groove 531 in conjunction with the rotating shaft 52. The torsion arm 541 of the torsion spring 54 abuts against the bottom of the torsion spring mounting groove 531. The switch mounting groove 512 has a triangular cross-section, allowing the rotating component 53 to be oscillatingly mounted within it. The triangular cross-section of the switch mounting groove 512 provides greater oscillation space for the rotating component 53. Under the torque of the torsion spring 54, the torsion arm 541 pushes the bottom of the switch mounting groove 512, keeping the rotating component 53 always pushed towards one side of the switch mounting groove 512. When the torsion spring 54 pushes the rotating component 53 against one side of the switch mounting groove 512, the switch mounting groove 512 limits the position of the rotating component 53, preventing the torsion arm 541 from further pushing the rotating component 53, thus fixing the position of the rotating component 53. When the rocker arm 6 pushes the rotating part 53, the rotating part 53 is limited by the switch mounting slot 512 and cannot continue to swing, thereby pushing the switch push block 51 to move.

[0050] Furthermore, the bottom of the rotating component 53 is provided with a first pushing surface 532 and a second pushing surface 533. In this embodiment, in the initial state, the umbrella cover plate 4 is closed onto the umbrella slot 11, the hook head 511 extends into the buckle hole 422 for engagement, and the switch push block 51 locks the umbrella cover plate 4 to prevent it from opening. At this time, the rocker arm 6 is located on one side of the first pushing surface 532. When the rocker arm 6 pushes towards the first pushing surface 532, the hook head 511 extends out of the buckle hole 422, the return spring 55 is compressed and deformed and stores elastic potential energy. When the hook head 511 is fully extended out of the buckle hole 422, the switch push block 51 will release the lock on the umbrella cover plate 4, and the pull... The force spring 121 releases elastic potential energy to open the parachute cover 4. At the same time, the rocker arm 6 moves away from the rotating part 53 due to its circular swing. Because the rocker arm 6 contacts the pushing force on the rotating part 53, the return spring 55 releases elastic potential energy to reset the switch push block 51. At this time, the rocker arm 6 is close to the side of the second push surface 533. When it is necessary to return the rocker arm 6 to its initial position, the servo motor 7 controls the rocker arm 6 to swing back. The rocker arm 6 pushes towards the second push surface 533, and the rotating part 53 swings backward due to the pushing force. After the rocker arm 6 is fully reset, under the torsion of the torsion spring 54, the torsion arm 541 pushes the bottom of the switch mounting slot 512, swinging the rotating part 53 back to its original position, preparing for the next parachute opening.

[0051] In this embodiment, the parachute ejection device 3 includes a parachute pusher 31, an ejection spring 32, a spring fixing block 33, and a spring fixing seat 34. The spring fixing seat 34 is installed at the bottom of the parachute slot 11. One end of the ejection spring 32 is fixed to the spring fixing seat 34, and the other end of the ejection spring 32 is connected to the parachute pusher 31 in conjunction with the spring fixing block 33. The deceleration parachute 2 is placed on the parachute pusher 31. The spring force provided by the ejection spring 32 pushes the parachute pusher 31, and the parachute pusher 31 presses the deceleration parachute 2 against the parachute cover plate 4. When the parachute cover plate 4 is opened, the ejection spring 32 releases elastic potential energy to eject the deceleration parachute 2 from the parachute slot 11. The ejected deceleration parachute 2 provides a deceleration effect to the model aircraft 200.

[0052] In this embodiment, the model aircraft deceleration parachute system 100 also includes a hatch 8, which can be flipped and installed on the deceleration parachute cabin 1. The hatch 8 is located above the parachute cover plate 4. When the parachute cover plate 4 is opened, the parachute cover plate 4 is pushed toward the hatch 8 to open the hatch 8.

[0053] Furthermore, in this embodiment, the hatch 8 is made of a metallic magnetic material and is magnetic. A magnet fixing seat 14 is provided in the first groove 12. The magnet fixing seat 14 is provided with a plurality of magnets 141 for attracting the hatch 8. When the hatch 8 is closed, the magnets 141 attract the hatch 8 to prevent the hatch 8 from opening.

[0054] Furthermore, the buckle 421 is provided with a first inclined surface 423, and the hook 511 is provided with a second inclined surface 5111. In this invention, when the deceleration parachute pack 2 needs to be installed on the deceleration parachute compartment 1, the deceleration parachute pack 2 is first pressed onto the parachute pack ejection device 3, and then the parachute pack cover plate 4 is closed onto the parachute pack groove 11. At this time, the first inclined surface 423 will abut against the second inclined surface 5111. Due to the pushing force, the second inclined surface 5111 causes the switch push block 51 to move outward. When the buckle opening 422 is aligned with the hook 511, the hook 511 enters the buckle opening 422 for engagement. At this time, the parachute pack cover plate 4 is locked by the switch push block 51 and cannot be opened. Finally, the compartment door 8 is closed, and the magnet 141 attracts the compartment door 8, thus completing the installation steps.

[0055] The following is the deployment and recovery method of the deceleration parachute 2 of the present invention, comprising the following steps:

[0056] In the initial state, the parachute cover 4 is closed on the parachute groove 11, the hook 511 extends into the buckle hole 422, and the switch push block 51 locks the parachute cover 4 on the parachute groove 11.

[0057] S1. Deceleration Parachute Departure: The servo motor 7 controls the rocker arm 6 to rotate, pushing the rocker arm 6 towards the first push surface 532 of the rotating component 53. The rotating component 53 cannot rotate under the action of the torsion spring 54. The rotating component 53 drives the switch push block 51 to move backward, causing the hook head 511 to leave the latching hole 422. At the same time, the return spring 55 is compressed and deformed and stores elastic potential energy. When the hook head 511 is fully extended out of the latching hole 422, the switch push block 51 will release the lock on the parachute cover plate 4. The tension spring 121 releases its elastic potential energy to open the parachute cover plate 4. The parachute ejection device 3 ejects the deceleration parachute 2 after it breaks through the parachute cover plate 4 and the door 8. At the same time, the return spring 55 releases its elasticity to reset the switch push block 51.

[0058] S2. Deceleration Parachute Recovery: First, press the deceleration parachute 2 onto the parachute ejection device 3, then cover the parachute cover 4 onto the parachute slot 11. At this time, the first inclined surface 423 will abut against the second inclined surface 5111 and push downward. Due to the thrust, the second inclined surface 5111 causes the switch push block 51 to move outward. When the latch 422 aligns with the hook 511, the hook 511 enters the latch 422 for engagement. At this time, the parachute cover 4 is locked by the switch push block 51 and cannot be opened. The servo motor controls the rocker arm 6 to swing back. The rocker arm 6 pushes towards the second push surface 533 of the rotating part 53. The rotating part 53 swings backward due to the thrust. When the rocker arm 6 is fully reset, the rocker arm 6 leaves the rotating part 53. Under the torque of the torsion spring 54, the torsion arm 541 pushes the bottom of the torsion spring mounting slot 531, causing the rotating part 53 to abut against the switch mounting slot 512.

[0059] This invention relates to a model aircraft deceleration parachute system. In this invention, the servo motor 7 controls the rocker arm 6 to push the unlocking component 5 to disengage from the parachute cover plate 4, causing the parachute cover plate 4 to open the parachute slot 11. The parachute ejection device 3 provides thrust to push the deceleration parachute 2 outward, causing the deceleration parachute 2 to pop out of the parachute slot 11. After popping out, the deceleration parachute 2 provides a deceleration effect to the model aircraft 200.

[0060] Meanwhile, in this invention, the deceleration parachute pack 2 can be directly installed into the parachute pack slot 11 first, and then the rocker arm 6 can be returned to its original position via the servo motor 7. When the rocker arm 6 returns to its original position, it pushes towards the second push surface 533 of the rotating component 53, causing the rotating component 53 to swing backward due to the pushing force. After the rocker arm 6 has fully returned to its original position, it moves away from the rotating component 53. Under the torque of the torsion spring 54, the torsion arm 541 pushes the rotating component 53, swinging it back to its original position, preparing for the next parachute deployment. This invention eliminates the need to first return the rocker arm 6 to its original position before installing the deceleration parachute pack 2, effectively simplifying the operation steps and improving the user experience.

[0061] This invention relates to a model aircraft drag chute system. A servo motor controls a rocker arm to release the locking assembly from the parachute cover. The unlocking assembly automatically resets under the action of a return spring. This invention, through its ingenious mechanical structure design, eliminates the need to reset the rocker arm before installing the drag chute, improving the user experience.

[0062] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
